Defined in header `<cmath>`

float exp( float arg );

double exp( double arg );

long double exp( long double arg );

Computes the e (Euler's number, 2.7182818) raised to the given power arg

arg - floating point value

e raised to the power arg

If the result is too large for the underlying type, range error occurs and HUGE_VAL is returned.

ln(x)

)
(function)

raises a number to the given power (

x y
